Hello there folks,
I have an underactive thyroid caused by Hashinmoto's and I am currently taking 75mcg T4 and 25mcg T3 under the supervision of an Endocrinologist.
Since starting on treatment the Endos have repeatedly warned about the dangers of over replacing, saying it can cause heart arrhythmias. Now, with my current blood test results and the treatment I'm on at the moment I'm not too worried about this, but I was wondering, if I did have heart arrhythmias and they were dangerous, would I recognise them? And was wondering if anyone had experience of this?
Before I was diagnosed, I had what I now recognise to be a lot of hyper symptoms for a period of time, I was anxious, panicky, thirsty all the time, using the loo all the time, sweating, found it difficult to eat, dizzy spells, nosebleeds, and heart beating like crazy, and it generally felt like everything was speeded up. So I feel like I would recognise if I was over replacing and at risk of the heart arrhythmias I've been warned about.
But I was wondering if they always went along with hyper symptoms or has anyone experienced heart palpitations, etc, while not feeling hyper in any other way?
And has anyone had experience of heart issues related to over replacement/being hyperthyroid, that were dangerous and needed treatment, and if so, how did you feel otherwise, normal or hyper?
Thanks for reading this very long question
